THOMAS H. RAE, or FARMINGTON', CALIFORNIA.

AXLE-SET.

Application filed August 26, 1912.

To all whom it may concern Be it known that I, THOMAS H. Ran, a citizen of the United States, residing at Farmington, in the county of San Joaquin,

.State 0-: California, have invented certain new and useful Improvements in Axle-Sets; and I do declare the following to be a clear, full, and exact description of the same, such as will enable others skilled in the art to which it apperta-ins to make and use the same, reference being had to the accompanying drawings, and to the characters ozt' reference marked thereon, which form a part o't this application.

This invention relates to in'iprovements in means. for setting axles at the proper angle as is necessary to the perfect operation of the wheels uponsuch axles, the object of the invention being to produce a tool by means of which the exact degree at which the axle is to be set can be dctern'lined without the need of computing the same from measurements and figures.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly efr'ective for the purposes for which it is designed.

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

On the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a top plan View of the complete device. Fig. 2 is a fragn-ientary view of the same showing it in use. Fig. 3 is a sectional view of a portion of an adjustment frame. Fig. 4 is a top plan view of an extension member. Fig. 5 is a side elevation of an adjustment pin. Fig. (3 is a sectional view of an indicator. vation of a guide.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates a straight member provided with an elongated slot 2 in one end and with a recess 3 in its top face to receive the head of a bolt hereinafter described, disposed over one side of which recess is a plate 1.

The numeral 5 designates an adjustment bar or guide frame pivotally mounted on the member 1 as at 6 and provided with a guide slot 7 in its lower end, which slot 7 is Fig. 7 is a side ele- Specification of Letters Patent.

disposed just above the recess 3. The member 5 is also provided on its end with a transverse slotted guide 8 secured thereto through which projects a bolt 9 carrying a wing nut 10, which bolt 9 is securcd in the member 1, whereby by the operatlon of the :wing nut 10, the guide 8 and incidentally the member 5 will be lixed stationary with respect to the member 1,. The member 5 is provided with an adjustable extension 5 at one end having a fork 5 which. its over the end at the member 5 and is adjustable thercon, any desired fixed. position of the member 55" with respect to the member 5 being determined by a wing nut 5 which is mounted on the bolt (3 and adapted to impinge against the members 5 and 5.

Mounted on the member 5 is a transverse slotted indicator 1.1 which is adjustable longitudinally along said member 5 and which may be secured in place by means of a bolt 12 and wing nut 13, which bolt 12 projects through the slot 7 and its l rad bearing 1 against the member 5 on. each. side of the espect to said member slot 7 and projecting into the recess 3 and then when the wing nut 13 is screwed down 1t clamps the member 11 stationary with bald member 11 is also similarly ad ustable transversely across the member 5 by means of its slot 14 through which the bolt 12 projects.

The numeral 1.5 designates bars provided with curved yokes lb, which members 15 are secured to each end of the member 1,

one of said members 1.5 being adjustable along the length of said member 1 by means of a bolt 17 which projects through the slot 2 and a wing nut 18 mounted thereon, there ,being a projecting flange 19 on the member 15 to keep it from turning with respect to the member 1.

Screwed into one end of the member 5 is a pin 20 having a threaded portion 21 provided with sixteen threads to the inch. Said pin 20 is provided with linger operating member 22 whereby it may be turned on its threads.

The numeral 23 designates a nut which abuts against the member 5 to determine the normal position 01 the pin 20, which normal position is such that the length of said pin projecting beyond the member 5" is equal to the length of the member 15.

The operation of the device is as follows:

When it is desired to set the axle, the lower end of the member 5 is set at a definite position with relation to the member 1. The member 1 is disposed against the outsides of the fellies 24 of the wheel for which the axle is to be set and then the indicator 11 is projected across to engage the side of the lower end of one of the spokes 25 which action causes the position of the indicator 11 to indicate the depth of the dish of the wheel. The indicator 11 is then set in fixed position by means of the wing nut 13 and then the member 5 is moved on its pivotal point 6 by means of the slotted guide 8 until a projecting flange 11 on the indicator bears against the plate a which thus moves the member 5 at its outer end a proportionate distance. This position of the member 5 is then fixed by the operation of the wing nut 10. The entire device is then mounted on the axle 26 just outside the collars 27 by means of the mem bers 15, the yoke 16 fitting over he axle 26 just outside the collar 27 as shown in Fig. 1 and on top of the axle. The member 20 is then at such a position that its end designates the point at which the spindle 28 of the axle must be bent to provide for the dish of the wheel for such spindle provided such spindle was not tapered, but inasmuch as the spindle is tapered, a further adjustment is necessary and thus this is accomplished by turning the pin 20 on its threaded portion 21, one or more turns as indicated by the finger members 22 until such pin 20 has been moved a suflicient distance to compensate for the taper of the member 28. F or instance, if the member 28 had a taper of an eighth of an inch and the pin 20 had siX- teen threads to the inch, then the member 20 would be turned one turn which would move it one-sixteenth of an inch which is necessary to compensate for one-half of the one-eighth taper of the member 28 and then when the spindle 28 is bent to touch the end of the member 20, it will then be set at the proper angle to compensate for the dish of the wheel and for its taper which will fully appear in the foregoing description. One of the members 15 which is adjustable as de scribed is movable as may be found desirable for different lengths of the axles.

The above operation describes the method of setting the spindle for compensating for the dish of the wheel and the device can also be used for setting the axle for the gather of the wheel by the following operation, namely: The member 5 is set parallel with respect to the member 1 and the member 20 is screwed up until the nut 23 abuts against the member 5 The yokes 16 are then fitted against the side of the spindle 28 and the spindle 28 then is bent to touch the end of the member 20 which then gives the set necessary to compensate for the gather of the wheels.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfils the objectsof the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such device may be resorted'to as do not form a departure from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

l. A device of the character described comprising a straight member, a guide frame pivotally mounted on said straight member and normally projecting longitudinally therewith, an indicator disposed trans versely on said guide frame and being adjustable thereon, means for fixing said guide frame stationary with respect to said straight member, and means for fixing said indicator stationary with respect to said guide frame, as described.

2. A device of the character described comprising a straight member, a guide frame pivotally mounted on said straight member and projecting normally longitudinally therewith, means for fixing said guide frame stationary with respect to said straight member and an indicator adjustable longitudinally and transversely on said guide frame, as described.

3. A device of the character described comprising a straight member, a guide frame pivotally mounted on said straight member, an adjustable extension on said guide frame, an indicator adjustably mounted on said guide frame, means for fixing said guide frame stationary with respect to said straight member, and a pin disposed at right angles to the outer end of saidextension, as described.

a. A device of the character described comprising a straight member, a guide frame pivotally mounted on said straight member, means for fixing said guide frame stationary with respect to said straight member, an indicator adjustable on said guide frame, said indicator being provided with a flange adapted to engage the side of said straight member, as described.

In testimony whereof I affix my signature in presence of two witnesses.
